Monday January 14th. astronomical 1805.
Observed an Eclips of the Moon. I had no other glass to assist me
in this observation but a small refracting telescope belonging to my
sextant, which however was of considerable service, as it enabled me
to define the edge of the moon's immage with much more precision
than I could have done with the natural eye. The commencement
of the eclips was obscured by clouds, which continued to interrupt me
throughout the whole observation; to this cause is also attributable
the inacuracy of the observation of the commencement of total darkness.
I do not put much confidence in the observation of the middle of the
Eclips, as it is the wo[r]st point of the eclips to distinguish with
accuracy. The two last observations (i.e.) the end of total darkness and
the end of the eclips, were more satisfactory; they are as accurate as
the circumstances under which I laboured would permit me to make
them.—
